Patent number: 11549522Abstract: An ejector includes a nozzle, a needle and a body. The nozzle reduces a pressure of a fluid and discharges the fluid as an injected fluid from a fluid injection port. The body includes a fluid suction port and a pressure increasing portion. The fluid suction port draws, as a suction fluid, a fluid from an outside of the body by using a suction force generated by the injected fluid. The pressure increasing portion increases a pressure of a mixture of the injected fluid and the suction fluid. The nozzle includes a throat portion and a nozzle-side tapered portion. The throat portion reduces a passage cross-sectional area of the fluid passage to be smallest in the fluid passage at the throat portion. The nozzle-side tapered portion expands the passage cross-sectional area of the fluid passage toward the downstream side in the flow direction of the fluid.Type: GrantFiled: June 26, 2019Date of Patent: January 10, 2023Assignee: DENSO CORPORATIONInventors: Tatsuhiro Suzuki, Gota Ogata, Yoichiro Kawamoto, Ryu Fukushima

The retaining ring is adapted for retaining the cap on the coating material dispenser with the plurality of orifices in the spatial orientation. The retaining ring includes first and second members. The second member is adapted for coupling to the coating material dispenser. The first member includes a first torque limiting driving member. The second member includes a second torque limiting driven member for engaging the first torque limiting driving member to limit the torque which the second member can apply to the coating material dispenser in response to manipulation of the first member.Type: GrantFiled: November 19, 2004Date of Patent: November 20, 2007Assignee: Illinois Tool Works Inc.Inventors: Kevin L. Alexander, Michael C. Rodgers

Patent number: 7296760Abstract: A valve for controlling the flow of a gas or mixture of gases through a passageway in a coating material dispensing device includes first and second valve portions. The first valve portion is adjustable with respect to the second valve portion selectively to adjust the flow through the passageway. One of the first and second valve portions includes a first engagement member and the other of the first and second valve portions includes a second engagement member. Engagement of the first and second engagement members indicates the relative orientation of the first and second valve portions.Type: GrantFiled: November 17, 2004Date of Patent: November 20, 2007Assignee: Illinois Tool Works Inc.Inventors: Kevin L. Alexander, Michael C. Rodgers

Patent number: 7185830Abstract: A liquid spray nozzle configured to provide a relatively uniform droplet size spray having a nozzle body, a flow passage disposed in the nozzle body, a turbulent flow mechanism in the flow passage, a flow separating mechanism in the flow passage and a converging mechanism at the nozzle body outlet. The turbulent flow mechanism, preferably a cylindrical pin, induces turbulent flow to the fluid stream flowing through the passage. The flow separating mechanism, also preferably a cylindrical pin, separates the turbulent flow into two separate, diverging streams. The converging mechanism is configured to direct the two streams together such that the colliding thereof produces a spray made up of substantially uniform sized droplets. Preferably, the converging mechanism is an orifice plate having two outwardly extending deflecting members and a generally oval-shaped opening and the nozzle body is adapted to threadably connect to a hose or other conduit.Type: GrantFiled: June 18, 2004Date of Patent: March 6, 2007Inventor: David B. Malcolm

Patent number: 7178744Abstract: The invention relates to an apparatus and process for solid-state deposition and consolidation of powder particles entrained in a subsonic or sonic gas jet onto the surface of an object. Under high velocity impact and thermal plastic deformation, the powder particles adhesively bond to the substrate and cohesively bond together to form consolidated materials with metallurgical bonds. The powder particles and optionally the surface of the object are heated to a temperature that reduces yield strength and permits plastic deformation at low flow stress levels during high velocity impact, but which is not so high as to melt the powder particles.Type: GrantFiled: November 22, 2004Date of Patent: February 20, 2007Assignee: Innovative Technology, Inc.Inventors: Ralph M. Tapphorn, Howard Gabel

Patent number: 7086613Abstract: A solenoid-operated liquid spray gun having a lightweight, corrosion resistant plastic housing which enables the spray gun to be mounted on and be more easily moved by robotic transfer devices. To effect the necessary flux loop within the plastic-housed spray gun for reciprocating a valve plunger in response to energization of the solenoid coil, the spray gun includes a radially disposed flux-directing member adjacent at least one end of the coil. The flux-directing member, while extending radially outwardly a distance less than the diameter of solenoid coil, effects efficient flux direction for operating the solenoid notwithstanding the lack of a magnetic conductive medium provided by the metal housing of conventional solenoid-operated spray guns.Type: GrantFiled: January 24, 2003Date of Patent: August 8, 2006Assignee: Spraying Systems Co.Inventor: Timothy H. Hennessy

Patent number: 7077339Abstract: An applicator for applying a multi-component bio-material including at least two containers. Both containers are held in a structure or oriented in a structure such that material contained in the containers can be expressed from oriented outlets simultaneously. The applicator includes a graspable member which allows the material to be expressed from all containers of the applicator substantially simultaneously. The applicator may be constructed such that a pre-selected and substantially different volume is expressed from each of the containers substantially simultaneously.Type: GrantFiled: February 3, 2003Date of Patent: July 18, 2006Assignee: Biomet, Inc.Inventor: Michael D Leach

Patent number: 6997401Abstract: A fuel injector adapter for providing nitrous oxide to an internal combustion engine is disclosed. The nozzle has a fuel injector passage, having a central axis and terminating at an injector outlet, for passing fuel from a fuel injector to an engine. The nozzle also has one or more first auxiliary passages, which may be arranged in an annular pattern around the fuel injector passage, and which terminate at first outlets. The nozzle furthermore may have one or more second auxiliary passages, which also may be arranged in an annular pattern around the fuel injector passage, and which terminate at second outlets. The first auxiliary passages and second auxiliary passages are adapted to supply nitrous oxide or other additional combustion reactants to the engine. The nozzle may be attached to an engine intake and may be adapted to fit between a fuel injector and an engine without substantial modification to the engine.Type: GrantFiled: January 6, 2004Date of Patent: February 14, 2006Assignee: Holley Performance Products, Inc.Inventors: Oswald Baasch, Douglas Joseph Flynn, Laura Beth Rucker, Shane Wilson
